f The back plate v-i's provided With an eject ing opening 36, and4 toV eject thecoin therethroughV I 'providelan ejecting' stud 37, which Y is normally held in place by the vaction of the spring 38 to Whichit isattached, which Y spring is in turn fastened by a'rivetj39 to the casing.l The ejecting-stu-d engages theedo'e 'of a coin when its rear edge passes .over t 1e shoulder 40 ofrthe recess 41 lin the front plate, (which, is opposite theedge'of the ejectf ing openingand the coin is thus lshot through into a suitable'receptacle or intol the bottom usually recessed, as at 45, so as to be engagedby the inner edge of the perforation in a slug or washer 46,which will' be seen clearly from Figure 9.

Normally both studs are pressed outward because they are engaged by the slide, as will beseen fromfFigures 2 and 7 but when the slide is moved forward, even if the slugis of thefproper thickness, both studs will enter into the perforation in the coin, being snapped into place by the springs to which they are fastened, and the inner edge of the perforation will be engaged by the arresting stud 42 and the slide can not complete its movement, which complete vmovement is necessary for the operation of the delivery mechanism. VThen when the operating handle isv turned back the slug or washer will be presented again at the ins'ertionslot, be'-V cause on* its return it .engages first the ejecting stud,7 its tapered edge Yforming a little cam` surface which pushes it back and it carries with it the spring 43, and consequently thefstud 42, far enough so that the tapered face 44 of the arrestingvstud will also lbeV en'- Y gagedand slid 'back to the position shown they engage therear'edge ofthe coin recess in Figure 7 vTheseinclined faces also provide forthesestuds being pushedback when 15 in the slide 14. Y n Y* There is thus an adequate security against lany fraudulent operation of thevilock by a coin that yis toolarge in diameter, by one that is too small in diameter or by a perforated slug, suchfas` a washer.
